As with any new and emerging technology, security should be addressed early in terms of understanding the requirements, participating in the evaluation of products and related technologies, and finally in the engineering, design, and implementation of new applications and systems. Security should also be considered during all phases of the systems development life cycle. This is nothing new, and many of us have learned this lesson painfully over the years as we have tried to retrofit security solutions as an adjunct to the implementation of some large and complex system. Another important point to consider throughout the integration of new technologies, is “technology does not drive or dictate security policies, but the existing and established security policies drive the application of new technologies.” This point must be made to management, customers, and supporting IT personnel.

For most of us, the WWW will be one of the most universal and influential trends impacting our internal enterprise and its computing and networking support structure. It will widely influence our decisions to extend our internal business processes out to the Internet and beyond. It will enable us to use the same user interface, the same critical systems and applications, work towards one single original source of data, and continue to address the age-old problem: how can I reach the largest number of users at the lowest cost possible?”

THE PATH TO INTERNET/BROWSER TECHNOLOGIES

Everyone is aware of the staggering statistics relative to the burgeoning growth of the Internet over the last decade. The use of the WWW can even top that growth, causing the traffic on the Internet to double every six months. With five internal Web servers being deployed for every one external Web server, the rise of the intranet is also more than just hype. Companies are predominately using the Web technologies on the intranet to share information and documents. Future application possibilities are basically any enterprise-wide application such as education and training; corporate policies and procedures; human resources applications such as a resume, job posting, etc.; and company information. External Web applications include marketing and sales.

For the purpose of this discussion, we can generally think of the Internet in three evolutionary phases. While each succeeding phase has brought with it more utility and the availability of a wealth of electronic and automated resources, each phase has also exponentially increased the risk to our internal networks and computing environments.

Phase I, the early days, is characterized by a limited use of the Internet, due in the most part to its complexity and universal accessibility. The user interface was anything but user friendly, typically limited to the use of complex UNIX-based commands via line mode. Security by obscurity was definitely a popular and acceptable way of addressing security in those early days, as security organizations and MIS management convinced themselves that the potential risks were confined to small user populations centered around homogeneous computing and networking environments. Most companies were not externally connected in those days, and certainly not to the Internet.

Phase II is characterized by the introduction of the first versions of data base search engines, including Gopher and Wide Area Information System (WAIS). These tools were mostly used in the government and university environments and were not well known nor generally proliferated in the commercial sector.

Phase III brings us up to today’s environment, where Internet browsers are relatively inexpensive, readily available, easy to install, easy to use through GUI frontends and interfaces, interoperable across heterogeneous platforms, and ubiquitous in terms of information access.

The growing popularity of the Internet and the introduction of the “Internet” should not come as a surprise to corporate executives who are generally well read on such issues and tied into major information technology (IT) vendors and consultants. However, quite frequently companies continue to select one of two choices when considering the implementation of WWW and Internet technologies. Some companies, who are more technically astute and competitive, have jumped in totally and are exploiting Internet technologies, electronic commerce, and the use of the Web. Others, of a more conservative nature and more technically inexperienced, continue to maintain a hard-line policy on external connectivity, which basically continues to say “NO.”

Internet technologies offer great potential for cost savings over existing technologies, representing huge investments over the years in terms of revenue and resources now supporting corporate information infrastructures and contributing to the business imperatives of those enterprises. Internet-based applications provide a standard communications interface and protocol suite ensuring interoperability and access to the organization’s heterogeneous data and information resources. Most WWW browsers run on all systems and provide a common user interface and ease of use to a wide range of corporate employees.

Benefits derived from the development of WWW-based applications for internal and external use can be categorized by the cost savings related to deployment, generally requiring very little support or end-user training. The browser software is typically free, bundled in vendor product suites, or very affordable. Access to information, as previously stated, is ubiquitous and fairly straightforward.

Use of internal WWW applications can change the very way organizations interact and share information. When established and maintained properly, an internal WWW application can enable everyone on the internal network to share information resources, update common use applications, receive education and training, and keep in touch with colleagues at their home base, from remote locations, or on the road.
